Fix setting a config value in kconfig-inclusions when there's already a conflicting existing value in defconfig. For example, setting CONFIG_SYSTEM_TRUSTED_KEYS would have no effect, because there would already be a setting for this specified by Debian's default config. With this, it _might_ be possible to remove the need for kconfig-force-inclusions, but that still needs to be checked. Signed-off-by: Saikrishna Arcot <sarcot@microsoft.com>
Becuase of kpatch-inclusions having quotes around the string, but the value from `scripts/config` having the quotes stripped, the comparison fails due to one side having quotes but the other side not having quotes. This effectively adds support for setting string kconfigs in kconfig-inclusion. Signed-off-by: Saikrishna Arcot <sarcot@microsoft.com>
